FRANK SKI BA BY KM,

HIS ATTORNEY United States Patent 3,191,218 HINGE STRUCTURES WITH MULTIPLE PINTLES Frank Skiba, Yonkers, N.Y., assignor of twenty-five percent each to Stanley M. Skiba, Sam Sokololf, and Seymour Levy Filed Dec. 3, 1963, Ser. No. 327,701 6 Claims. (Cl. 16-163) The invention relates to hinges and relates more particularly to a novel hinge construction of sheet metal and provided with multiple pintles.

An important object of the invention is to provide an inexpensive hinge formed entirely of sheet metal, except for the pintles, and which is particularly useful for hinged doors and the like on small sheet metal building structures.

Another object of the invention is to provide a flush mounted hinge wherein the portions corresponding to the pintle-receiving knuckles are simply stamped and formed from sheet metal.

The hinge of the present invention is formed from two angle members, each provided with first and second flanges having an angular relation to each other. The first flanges of each of the angles may be substantially co-planar when a door supported thereby is in closed position. The two-pintle arrangement of the present invention gives greater flexibility to the hinge in the door-closing action and knuckles, as such, are eliminated. In their place, the corner sections of each angle are struck inwardly to form short inner channels which receive the pintles which pass through the ends of a link which may be a continuous flattened loop with curved ends to receive the pintles. Alternatively, the link may be a flat piece of metal with its ends curved to form loops extending around the pins.

The pintles are somewhat longer than the struck-in channels and the opposed ends of the pintles extending above and below the channel are received in the inner angular corners of the angle members.

Another object of the invention is to provide struckin channels in the corner sections of the angles which receive the intermediate portions of the pintles, the struckin sections being formed without stretching of the metal which would tend to produce cracks.

The hinge of the present invention is particularly useful for mounting doors in sheet metal building structures and housings generally. The angle member on the fixed side of the hinge may be a part of the structure or it may be separately applied as by welding or otherwise. The other angle may be the margin of the door in which case it will be a metal plate with an angular flange along the edge.

In the drawing,

FIG. 1 is a front elevation of a structure with a hinged door employing the hinge of the present invention;

FIG. 2 is a broken section taken on line 2-2 of FIG. 1;

FIG. 3 is a broken section taken on line 33 of FIG. 1;

FIG. 4 is an enlarged detail view showing the pintles in broken lines;

FIG. 5 is a perspective view showing one form of link or loop connecting the pintles;

FIG. 6 shows an alternative loop;

FIG. 7 shows a modified form of pintle;

FIG. 8 is a broken plane view showing a different angular relation between the second flanges of the angular members;

FIG. 9 shows still another modification in this angular relation.

The hinge of the present invention includes a pair of ice angle members 10 and 11, each having first and second flanges 12 and 14 at substantially right angles to each other and presenting an outer corner section 16 and an inner corner section 18, both of angular configuration. These corner sections have aligned, inwardly struck portions forming channels 19. In forming these channels, the direction of bend of the material is reversed from what it was when originally formed as an angle bar but the metal is not stretched which would place it under strain and produce cracks.

A link 20 formed from a single elongated sheet metal blank is bent into the shape of a flattened oval with generally fiat front and rear walls 21 and 22 the ends of the blank being in substantial abutting relation in this rear wall. The link further has opposed curved end sections 24- which are positioned in the channels and are secured therein by pintles 26 having heads 28 at one end thereof and which may be tapered at the opposite ends 29.

It was earlier pointed out that the two angle members may be separately applied or they may be part of the structure. The latter arrangement is shown in the drawings and when the hinged door member 11 is in the closed position of FIG. 2, the second angular flanges 12 and 14 are in face-to-face slightly spaced arrangement while the faces of the panel 10 and the door 11 co-planar with the outer surface of the links 20. In FIG. 2, the flange 12 is shown as having an angular extension 31 forming a weather stop.

FIG. 6 shows a modified form of link having a wall section 34 and opposed curved loops 36 which receive the pintles. These loops may be entirely closed or they may be slightly open as shown. The headed pintles 26 of FIG. 4 may be replaced by the pintle structure of FIG. 7 wherein the pintle 38 has a parallel section 39 connected by a reverse bend 40 the longer length of portion 39 enabling the hinge to be assembled with more facility.

In FIG. 8, plates 42 and 44 have flanges 46 and 48 which do not have a right angular relationship to the plates but they do have the same inwardly struck-in sections 49 and 50 which receive the pintles 51 passing the ends of lengths 52. In FIG. 9, the plates 54 and 55 have flanges 56 and 58 which are disposed at more than a right angle of the plane of the plates and these again have the inwardly struck channels 60 and 61 which receive the ,pintles 62 passing the curved ends of link 64. The hinge of FIG. 9 will be particularly useful if the door is to have a swinging movement of more than For instance, if plate 54 is part of a building structure and door 55 is on the corner and in closed position occupies the position shown in broken line A, the door can be swung 270.

While there have been described herein what are at present considered preferred embodiments of the invention, it will be obvious to those skilled in the art that many modifications and changes may be made therein without departing from the essence of the invention. It is therefore to be understood that the exemplary embodiments are illustrative and not restrictive of the invention, the scope of which is defined in the appended claims, and that all modifications that come within the meaning and range of equivalency of the claims are intended to be included therein.

What I claim is:

1. A hinge for a door or the like and formed from two angle members, each having first and second flanges disposed at an angular relation to each other, the first flanges of the members being generally co-planar when a door supported by the hinge is in closed position, the second flanges forming, with the first flanges, outer and inner angular corner sections, portions of said corner sections being struck inwardly to form short inner channels which are aligned with each other in the two angle members, a link of sheet metal whose ends are curved of the members being generally cor-planar when a door supported by the hinge is in closed position, the second flanges forming, with the first flanges, outer and inner. angular corner sections, portions of said corner sections being struck inwardly to form short inner channels which are aligned with each other in the two angle members, a link having the contour of a flattened oval with generally parallel sides and curved ends, the latter being positioned in said recesses, and pintles passing through said curved ends, the opposed ends of the pintles above and below said struck-in channels being supported by the angular corner sections which form knuckles for the pintles.
